When the continents of Io'Tamrin sank into the Dragon Sea, more than three-quarters of the dwarven kingdom of Gar Morra suddenly found itself underwater. The great mountains of Gar Morra now form rocky islands riddled with caves.
Freed from the tyranny of the dragonborn dynasties, the dwarves of Gar Morra returned to their ancestral kingdom to rebuild their strongholds, only to discover their islands overrun with orcs. For centuries now, the dwarves have been warring with these orcs, pushing them deeper down into the mountains. In the process, they’ve discovered large air pockets — vast cavern labyrinths filled with monsters far worse than orcs. The dwarves refer to this sprawling network of caverns as the Hollowdark ,and they would like nothing more than to rebuild their great kingdom in its protective depths.
In addition to rebuilding Gar Morra, the dwarves want to recuperate their lost wealth. Beneath the Dragon Sea lie the ruins of dwarf kingdoms and warded vaults filled with gold and other treasure that the dwarves aren’t willing to abandon. Consequently, the dwarves of Gar Morra are anxiously launching expeditions to these ancient sites to recover what they can.
